I am a Teacher Who is asked Questions by the Students, should I answer?

Question:

I am a teacher, a graduate from Intermediary College, Islamic Studies Section, and I have studied a number of Fiqh books. What is the ruling in my case when I am asked questions by my students and I answer, according to my knowledge, that is, by way of Qiyas [2] and Ijtihad, without going into the rulings of Haram and Halal?

Answer:

You should refer to the books and Ijtihad and then answer in accordance with what you perceive to be correct, and there is no objection to you doing this. However, if you are in doubt about the answer and the correct position is not clear to you, then say I do not know, and promise them that you will look into the matter and after investigation, answer them, or refer the matter to the scholars in order to ascertain them the truth.
